Support hot restart for DDC library bundle format (#162123)
https://github.com/dart-lang/webdev/issues/2516
https://github.com/dart-lang/webdev/issues/2561

- Adds logic to emit newly compiled sources to a file that can be read
by the bootstrapper.
- Adds bootstrapping logic to reload scripts as needed. This involves
implementing the necessary hot restart callback, fetching and processing
the emitted file of newly compiled sources, cache busting, and loading
the scripts onto the page. A lot of this logic is similar or identical
to what we have for internal hot restart support.
- Runs existing hot restart tests with the new bundle format.
- Adds meta tag to run with utf-8 like in
https://github.com/flutter/flutter/pull/161493.
- Uses DWDS 24.3.3.

Integration tests

These tests are not hermetic, and use the actual Flutter SDK. While they don't require actual devices, they run flutter_tester to test Dart VM and Flutter integration.

Use this command to run (from the flutter_tools directory):

../../bin/cache/dart-sdk/bin/dart run test test/integration.shard

You need to have downloaded the Dart SDK in your Flutter clone for this to work. Running ../../bin/flutter will automatically download it.

Coverage exclusion

These tests are expensive to run and do not give meaningful coverage information for the flutter tool (since they are black-box tests that run the tool as a subprocess, rather than being unit tests). For this reason, they are in a separate shard when running on continuous integration and are not run when calculating coverage.

Adding new test files

When adding a new test file make sure that it ends with _test.dart, or else it will not be run.
